ROWP SC HARVIZ SA sector Vlahita - Secondary Wastewater Treatment Plant in Vlăhița, Romania

ROWP SC HARVIZ SA sector Vlahita is a municipal wastewater treatment plant located in Vlăhița, Harghita County, Romania. The facility serves a population of 3,274 and operates with a designed capacity of 5,400 m³/day, currently discharging 532.33 m³/day of treated effluent. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. This level of treatment typically involves biological processes to reduce organic matter and suspended solids before discharge. The treated effluent is released into the local watershed, which ultimately drains into the Olt River basin. The Olt River flows southward through Romania, eventually reaching the Danube River and the Black Sea. The plant's operations help protect downstream water quality and aquatic ecosystems in this important river system.

The plant discharges into the Olt River basin, a major tributary of the Danube River that flows into the Black Sea. The Olt River supports diverse aquatic life and provides water for agriculture and communities downstream. The secondary treatment process reduces organic pollutants and suspended solids, helping to maintain the ecological health of the river and its receiving waters.
